马岭油田持续稳产技术

马岭油田已开发二十余年，进入高含水后期开发阶段，由于后备储量不足，稳产难度大．油田由于河流相沉积环境，储层非均质性强，注水开发后期仍存在着大量的剩余油．针对低渗透油藏后备储量不足、稳产难度大的现状，以稳产为中心，以挖掘油田潜力、提高最终采收率、降低投资和成本、提高经济效益为目标，开展了剩余油分布规律的研究，并针对剩余油的分布提出了六项使马岭油田持续稳产的开发技术，它在油田的持续稳产中起到了明显的效果．

Technological Measures for Stabilizing the Crude Oil Output of Maling Oil Field

Having been developed for over twenty years, Maling Oil Field is in the later stage of high water cut development. It is difficult to stabilize the crude oil output. The reservoirs of the oil field are very heterogeneous because of its sedimentary environment of fluvial facies. So there is a great deal of remaining oil in the later period of water flooding development. To make the crude oil output stable and increase ultimate recovery factor, the remaining oil distribution is studied, and six measures are proposed. It is proven that the measures have obvious effectiveness of stabilizing crude oil output.
